RESTful API's - Easy way to interact?

Hey,

I am working on my first full fledge application. Now, my problem lies within that all my data and the main functionality of my application is coming from a RESTful API application on the web. I am having trouble sending headers and configuring the authentication and it just cripples what I do have of my program. So, it would be helpful if someone could explain an easier way than what I am doing to access the RESTful API.

Here is the code I am using to set the headers:

NSString *requestURLWithHeaderAuth(NSURL *url, NSString *headerVal)
{
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"GET"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"Basic: %@", headerVal] forHTTPHeaderField:@"Authentication"];

return [[[NSString alloc] initWithData:[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil] encoding:NSUTF8StringEncoding] autorelease];
}

Now, I need to figure out how to use set GET, but I think that is working. The problem and it is crashing is because it is being encoded by every other method. Here is an example in "pseudo code":

'Basic ' + Base64.encode(username + ':' + password)


Hopefully someone will be able to help,
Jeremy

You can learn a lot about an individual just by reading through his code, even in hexadecimal." - Unknown
